Embodiment Construction

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0025] refer to Figure 1 to Figure 5 , this preferred embodiment provides a dimming device for LED lamps, including: such as Figure 4 The concave reflector 1 shown and as figure 2 For the truncated conical lens 2 shown, one end of the reflector 1 has a second circular opening 22 capable of fitting the lens 2, and the other end has a first circular opening 11 capable of emitting light. The diameter of the second circular opening 22 is larger than the diameter of the first circular opening 11 .

[0026] Through this device, such as figure 1 As shown, the light passing through the fully transparent lens reflects the light to the preset area on the radiation surface of the reflector 1, and the angle of refraction of the light that is not in the no...

Abstract

The invention discloses an LED (Light-emitting Diode) dimming device and an LED luminaire. The LED dimming device comprises a concave reflector and a circular cone-shaped lens, wherein a first circular opening capable of being connected with the reflector in a matching manner is formed at one end of the lens; a second circular opening capable of emitting light is formed at the other end of the lens; and the diameter of the second circular opening is less than that of the first circular opening. With the adoption of the LED dimming device and the LED luminaire, a utilization rate of the light is increased.

Description

technical field [0001] The invention relates to the lighting field, in particular to a dimming device for an LED lamp and the LED lamp. Background technique [0002] With the continuous development of LED technology and heat dissipation technology, high-power COB chips based on the integration of multiple LED chips have also appeared one after another. However, such an integrated COB chip has a relatively large surface area. [0003] Traditional LED lamps generally adopt the principle of primary light refraction or primary light reflection, only restricting part of the light to the area we set in advance, and part of the light is outside the range we set, and we can directly feel it with our naked eyes. Sets the afterglow outside the area. As a result, the utilization rate of light is relatively low, which greatly wastes energy. [0004] Aiming at the problem of relatively low utilization rate of light in related technologies, no effective solution has been proposed yet. ...
