Embodiment 1

[0022] Such as Figure 1 ~ Figure 3 As shown, the LED projection light source of this embodiment is a common MR16 type LED projection light source, including a lamp body 1, a lamp head connection part 2, a reflector lamp cup 3, an LED chip 5, a driving circuit assembly 6, and a cooling tube 4. The lamp head connecting part 2 is fixedly connected to the front end of the lamp body 1, the driving circuit assembly 6 is located in the inner cavity of the lamp body 1, and the heat dissipation tube 4 is embedded in the inner cavity of the lamp body 1 At the top, the LED chip 5 is fixed on the heat dissipation tube 4 and conducts heat and dissipates heat through the heat dissipation tube 4, and the drive circuit assembly 6 is electrically connected to the lamp cap connection part 2 and the LED chip 5 respectively, The reflector lamp cup 3 includes a lamp cup part 31 and a lens part 32. The lamp cup part 31 and the lens part 32 are made of a light-transmitting material and integrally f...

Embodiment 2

[0024] Such as Figure 4 ~ Figure 6 As shown, the difference between the LED projection light source of this embodiment and Embodiment 1 is that in this embodiment, the lamp body 1 is made of heat-conducting plastic, the reflector lamp cup 3 is made of plastic, and the lamp cap The model of the connection part 2 is GU5.3.

[0025] The remaining features of this embodiment are the same as those of Embodiment 1.

Abstract

An LED projection-type light source, comprising a lamp body (1), a lamp base connection part (2), a cup-shaped reflector lamp (3), an LED chip (5), a drive circuit assembly (6), and a heat dissipation tube (4); the lamp base connection part (2) is fixedly connected to the front of the lamp body (1); the drive circuit assembly (6) is located in the inner cavity of the lamp body (1); the heat dissipation tube (4) is embedded in the top of the inner cavity of the lamp body (1); the LED chip (5) is fixed on the heat dissipation tube (4), and conducts and dissipates heat via the heat dissipation tube (4); the drive circuit assembly (6) is electrically connected to the lamp base connection part (2) and the LED chip (5) respectively; the cup-shaped reflector lamp (3) comprises a lamp cup-shaped portion (31) and a lens portion (32) integrally formed and made from light-transmitting material; the lens portion (32) gathers together in the light exiting direction the light emitted by the LED chip (5); and the lamp cup-shaped portion (31) totally reflects the light emitted by the LED chip (5). The LED projection-type light source has a simple and ingenious structure, attractive appearance, and crystal-clear light emitting effect, and can be widely applied in the field of LED light sources.

Description

technical field [0001] The invention relates to an LED projection light source. Background technique [0002] At present, in the field of lighting, LEDs have been more and more widely used in light sources for lighting because of their advantages such as energy saving, high luminous efficiency, long life, and fast start-up. Among the light sources, small projected light sources such as GU10, MR16, MR11, PAR16 and PAR20 are widely used. The above-mentioned types of light sources have a common feature that there is a reflective lamp cup behind the light-emitting surface. The existing LED light source types can already be used It directly replaces the halogen light source of the above type, and the size is already the same as that of the halogen tungsten lamp, but the manufacturing material and appearance design have already caused aesthetic fatigue, and its structure is basically installed in the lamp body made of heat-conducting material. Group LED and lens, the appearance d...
