Problems solved by technology

From this point of view, adding mounting components will impair the design, so it is very difficult
[0012] For example, a structure in which the front panel is attached to the appliance case with screws or the like may be considered, but the screw heads are exposed, so there is a problem that the designability is reduced

Embodiment approach 1

[0046] figure 1 It is a cross-sectional view showing a schematic configuration of the LED lighting fixture according to Embodiment 1 of the present invention.

[0047] The LED lighting fixture 1 of the present embodiment is as figure 1As shown, it includes a main body 11 , an LED unit 12 , a front panel 13 , a reflector 14 , and a power supply unit 15 . Here, the LED unit 12 is formed by mounting four LED elements 122 on a substrate 121 . In addition, the reflector 14 has a reflective surface 143 and a connection surface 144 that continuously connects the respective reflective surfaces 143. The reflective surface 143 is formed so as to have small-diameter openings 141 facing the respective LED elements 122 and gradually increase from the small-diameter openings 141. The connection surface 144 (in this embodiment, the center of the reflection plate 14) has a hole 145. On the other hand, the front panel 13 has a convex portion 131 engaged with the hole, and the front panel ...

Embodiment approach 2

[0065] Figure 7 It is a cross-sectional view of main parts showing a schematic configuration of an LED lighting fixture according to Embodiment 2 of the present invention. In addition, for the same as that shown in Embodiment Mode 1 figure 1 The same structures are attached with the same reference numerals and their descriptions are simplified or omitted.

[0066] Figure 7 It is a sectional view showing the schematic structure of the LED lighting fixture 2 of this embodiment, Figure 8 shows the front view, Figure 9 A side view is shown. Figure 10 is a stereogram. In this embodiment, a motion sensor (human sensor) 30 using a pyroelectric element is used, and a red cap 135 incorporating a red LED element is provided as an indicator light for checking the operation mode of the sensor. Here, instead of the cap 132 in Embodiment 1, the red LED element 123 is mounted on the LED substrate 121 in the area corresponding to the protrusion protruding from the hole 145 of the ...

Abstract

The invention provides a lighting appliance, comprising: a plurality of LED components, a substrate for installing the LED components, a reflecting board provided with reflecting surfaces and a connecting part continuously connecting the respective reflecting surface, and a light-transmitting front surface panel disposed in a light illuminating direction of the LED components, wherein, either the connecting surface part or the front surface panel is provided with a hole part, and the other is provided with a protruding part, via clamping of the hole part and the protruding part, the front surface panel is fixed on the reflecting board.

Description

technical field [0001] The invention relates to an LED lighting appliance and a manufacturing method thereof, in particular to an LED lighting appliance which uses light-emitting elements such as LED (light-emitting diode) elements as a light source and has a reflector. Background technique [0002] Conventionally, LED lighting fixtures in which a front panel is supported by a fixture case have been proposed. For example, if Figure 11 As shown, the LED lighting fixture 4 accommodates an LED unit 42 in which a plurality of LED elements 421 are mounted, and a power supply unit 45 that supplies electric power for lighting the LED unit 42 inside a main body 41 . In addition, a reflector 44 is provided for each LED element 421 to reflect the radiated light, and a light-transmitting front panel 43 for preventing the LED element 421 from contacting the outside and providing electrostatic protection is mounted on the outside. [0003] Here, the reflecting plate 44 is formed in a b...
